IMPROVEMENT IN HARVESTER RAKING APPARATUS.

Specification forming part of Letters Patent No. R LO RS, dated January1, 1856.

To all whom it may concern:

Be it known that I, GEORGE A. CLARKE, of Philadelphia,inthecountyofPhiladelphia and State of Pennsylvania, have invented a newand useful Improvement in Harvesters; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to annexed drawings, making apart of this specification, inwhich Figure 1 is a plan or top view of my improve ment. Fig. 2 is adetached front view of the raking attachment.

Similar letters of reference indicate corresponding parts in the twofigures.

The nature of my invention consists in a raking attachment constructed,arranged, and operating as will be hereinafter fully shown.

To enable others skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents the frame of the machine, which is of rectangular form andsupported by two wheels, B B. (See Fig. 1.)

To the front end of the frame A the fingerbar 0 is attached, having theusual fingers, a,

secured-to it, in which fingers the sickle D works, the sickle beingalso of usual construction.

To the front end of the frame A, and in line with the sickle D at oneend of it, there is placed a small shaft, E, which has a wheel, F, hungupon it obliquely. (See Fig. 1.) The edge or periphery of this wheelworks between two small uprights, b b, on the end of the sickle 1). Theshaft E has a hub or boss, 0, permanently attached to it, which hub orboss is toothed or serrated on its outer edge, and on the shaft E thereis placed loosely a collar, d,

. having its inner edge toothed or serrated. The

teeth of the collar (1 are kept in gear with the teeth of the hub orboss 0 by means of a spiral spring, 6, which is placed around the shaftE. The collar (1 has teeth or projectionsfon its periphery.

G is a shaft attached to one side of the frame A, and on the outer endof which the wheel B is placed loosely. This wheel is attached to theshaft G, when desired, by a clutch, H, of usual construction, saidclutch being operated by a lever, I.

J is a pulley attached permanently to the shaft G, and having teeth 9 onits periphery, and K is a chain, which passes around the pulley J andaround the collar don the shaft E, the teeth on the pulley and collarfitting in the links of the chain. (See dotted lines, Fig. 1.)

L is alever, which has its fulcrum at h. The outer end of this lever isforked and tits over the shaft E between the inncrend of the spiralspring 0 and collar d. The outer end of the lever L extends a shortdistance beyond the lever I.

M is a rake, which is formed of teeth *5, attached to a rod,j, the endsof which are fitted looselyin slides it It, which work freelyonguiderods l l, attached to bars N N, placed in the frame A parallel withthe finger-bar G.

O 0 are two pulleys, which are attached to bars P P at the under side ofthe bars N N. The pulleys O O are placed at a requisite distance apart,and have an endless belt, Q, passing around them, to which belt anupright pin, m, is attached, said pin fitting in a slot, at, in a rod,j,attached to the slides k k of the rake M. One end of the rodj has a pinor rod, 0, passing transversely through it, which pin strikes againstprojectionsp on one of the bars N at the end of each stroke or vibrationof the rake, as will be presently shown. The endless belt Q. is drivenby a belt, a, which passes around the lower part of one of the pulleys Oand around a pulley, b, on a shaft, Q, which receives its motion fromthe shaft Gr.

It is a lever, which is attached by a pivot, q, to a bar, S, underneaththe bars N N. One end of this lever B is attached by an arm, T, to acatch, U, by a pivot, r. The opposite end of the lever B has an arm, V,attached to it, which arm is connected to a lever, W. The outer end ofthe lever W is attached by a pivot, s, to a projection, t, on one of thebars N. The inner end of the lever W has a slot, 10, made through it, inwhich a pin, 1;, attached to a rod, to, fits. The rod w slides on rodsor 00, attached to the bars P S, and has rods y g 3 attached to it.

X is a platform, which is fitted over the raking attachment, theplatform having grooves out in it to allow the rake-teeth t to workthrough.

Operation: As the machine is drawn along a reciprocating motion is giventhe sickle by means of the oblique wheel F, which is retated by means ofthe chain K, the collar d turns the shaft E in consequence of its teethbeing kept in gear with the teeth of the hub or boss 0 by the spiralspring 0, and if the sickle becomes clogged the wheel F and hub or boss0 will remain stationary, the collar 61 slipping around and compressingthe spring 0, and also moving the lever L and operating the clutch H, soas to throw the driving-wheel B out of gear with the shaft G. Thedriving apparatus is thereby rendered self-operating, and the sickle, incase of being choked, will be thrown out of gear at the proper time, andwill be prevented from injury or breakage. As the grain is cut by thesickle it falls over on the platform X, and the rake M is moved back andforth by the endless belt Q, which is operated by the belt a. WVhen therake M reaches the end of its backward stroke the teeth are elevated inconsequence of the pin 0 striking against the projection 19, and therake in movthrows the rods g backward, so that the grain will fall uponthe ground, and as the rake returns the rodj will draw upon the catch Uand 'force outward the rods 3 to their original position, so that therods will catch the grain that is cut opposite to them and retain ittill the rake again arrives at the end of the platform X.

The above invention is simple and effective and operates practicallywell.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

Operating the rake M by means of the endless belt Q, in combination withthe levers R W, connected with the rods y, as shown, for

the purpose of raking the cut grain from the platform X.
